This is a faithful replica of the old 80's 'shoot the aliens games' like invaders and galaxian.
I am not a big fan of those games and I don't like this much. However if you liked those games,
then you will like this.
Just incase there is someone out there who has not played one of these games before, here is a
brief decription: You control a ship and can move it left and right at the bottom of the screen.
The aliens move left and right at the top of the screen and you have to try and shoot as many of
them as possible. - Paul Crossland
